212 FAUNISTIC NOTES AT PLYMOUTH DURING 1893-4. 
subjects of which they treat; I shall endeavour to expand them 
both in scope and detail when further observations have been made 
and the time is ripe. 
Roscorr; June 380th, 1894. 
I. Faunistic Recorps. 
Hyprozoa.—Several additional colonies of Tubiclava cornucoprx 
have been obtained in 15 to 25 fathoms of water south of the 
Mewstone. In all cases they were growing, like our first specimen, 
on shells of Aporrhais or Turritella, tenanted by the Gephyrean 
Phoscolion strombi. Some of the colonies were young, and possessed 
a reticulate stolon, like Norman’s original specimens from the 
Shetlands—thus confirming my anticipation that the solid carpet- 
like base of large colonies is not a specific difference, but a senile 
character (Trans. Devon. Assoc., 1892, pp. 378-9). 
Clava cornea (of Hincks) is abundant on the fronds of Fucus 
growing in that branch of the Hamoaze known as the Lynher, or 
St. German’s River. 
In tide-pools under the Hoe two species of Clava are common, one 
bemg C. multicornis, and the other a larger and stouter form, which 
seems to be the Clava leptostyla of Hincks’s monograph. ‘To prevent 
confusion, however—since one of the characteristics of our form, at 
any rate, the purple colour of the gonophores, is nowhere mentioned, 
—I give its leading features here.—Colonies clustered, attached to 
stems of algee and to the floor of limestone pools; polyps very large 
and stout, tall when extended, of a rich salmon-flesh colour ; diges- 
tive cavity having a distinctly spiral marking, or even coiled appear- 
ance, which is seen when the polyps are fully extended as well as 
when contracted ; gonophores in two, three, four, or rarely five 
large compact round bunches immediately beneath the tentacles, 
and of a conspicuous purple colour when mature. 
Tubularia imdivisa has been dredged occasionally in Millbay 
Channel. Good colonies were obtained there on April 13th, 1894, 
but the gonophores were provided with very short stalks, and did 
not form pendulous racemes. With them were large colonies also 
of Tubularia larynx, crowded with gonophores. On March 9th a 
small colony of a Tubularia was dredged in Barn Pool, growing on 
some Ceramium or Polysiphonia attached to a root of Laminaria. 
The stems were without annuli, the tentacles were white, and there 
was a collar-like expansion below the hydranths, and I inferred the 
species to be the 7’. humilis of Hincks’s monograph. On the 19th, 
however, I collected some other colonies from tide-pools below the 
Hoe, and they resembled the preceding in almost all points except
